Research Progress on Modification of Copper Current Collector and Improve-ment of Electrochemical Performance of Lithium Metal Anode
摘要
Abstract
Lithium metal lithium batteries usually exhibit very high specific energy density with lithium metal as the negative electrode.However,due to the problems of rapid capacity decay and low safety,it is difficult to further develop.The causes of battery failure can be attributed to two points;firstly,during the charging and discharging process,the"hostless"lithium metal will grow dendrites during the deposition/stripping process,which not only makes the current distribution on the electrode surface uneven,but also easily pene-trates the separator and causes the battery to short circuit.The second is the infinite volume expansion of lithium metal,which will lead to cracks in the electrode material and ultimately affect the performance and life of the battery.Therefore,how to modify the interface and optimize the structure of the copper-based current collector,which is the commonly used substrate for lithium metal deposition/ex-traction,so as to effectively regulate the lithium deposition behavior and inhibit the dendrite growth and alleviate the volume expansion,is very important to improve the electrochemical performance of lithium metal batteries.In this paper,the functionalized copper-based current collectors for lithium metal batteries were introduced,and the surface composition regulation and microstructure design of cop-per-based current collectors were discussed.Finally,a variety of modification strategies for stable lithium metal anodes were systemati-cally summarized,which provided a certain reference for the practical application of lithium metal anodes in high energy density bat-tery systems.关键词
